HIP-35 is a calculator for hipsters.
It emulates the RPN (reverse Polish notation) mode of HP-35 from 1972. It runs a terminal UI built with ncurses that displays the current result on a display.
RPN makes it very easy to compute long expressions containing lots of brackets. When using it, you don’t need to think how terms are grouped anymore.
Additional features not included in the HP-35 calculator:
- The display now has two rows, displaying the X and Y registers instead of just X.
- There is space on the right to display the 10 general registers. Back in the day users had to write down which register stores what.
- User can also enter negative numbers using the ~ as the unary minus. HP35 only supposed the CHS (change sign) operation for that.
- There is no ARC key. ARC key had to pressed to enable the SIN, COS, TAN keys to compute ASIN, ACOS, ATAN. The latter keys are directly implemented in HIP-35.
- The number format on the display is automatically adjusted based on the range the number is in.
- The LASTX key from HP-35s is ported as it makes certain calculations much faster.
